An affordable clean-energy solution that empowers women salt and gari producers to adapt to climate change!
The cooking stove is a rectangular structure designed for agrifood processing. It measures approximately 2.5 meters in length and efficiently integrates two to four independent combustion chambers within a single frame. This system relies on a controlled air injection to manage the fire. A fan, positioned at the rear of each chamber and powered by batteries or solar panels, is manually operated via a switch to regulate the air supply for the combustion. This controlled process ensures a more complete combustion, which minimizes the release of toxic smoke and pollution compared to traditional methods. The stove utilizes locally available sustainable fuels, such as ecological charcoal or carbonized palm nut shells.
This technology is not yet validated.

Climate adaptability: Highly adaptable
Can operate with or without batteries, meaning it adapts both to weather variability and to households’ financial capacity.
Biodiversity: Positive impact on biodiversity
Significant reduction of wood fuel use and forest logging
Carbon footprint: Much less carbon released
The technology releases much less carbon compared to traditional methods such as wood fuel use. ECO SIKA produces no direct emissions during cooking, while traditional fuels continuously release significant amounts of CO₂. Additionally, the reduction in fuelwood demand helps prevent deforestation, further lowering carbon emissions
Environmental health: Greatly improves environmental health
Low agro-processing productivity: Inefficient traditional cooking systems limit the output and operational performance of gari and salt processing enterprises.
High processing costs: Excessive fuel consumption increases production expenses for small-scale processors.
Limited equipment efficiency: Traditional stoves may lose a substantial share of heat, reducing the energy available for processing.
Restricted enterprise capacity: Inefficient cooking equipment limits the quantity of agricultural products that can be processed within a given period.
Weak competitiveness: High production costs can reduce the ability of local processors to compete on price and expand their markets.
Limited modernization of processing: The continued use of inefficient equipment constrains improvements in productivity, operational efficiency and value addition.
Improves agro-processing productivity: ECO SIKA combines multiple combustion chambers with controlled air injection to improve processing efficiency.
Reduces fuel requirements: The stove is designed to reduce fuelwood demand by up to 50%, potentially lowering recurrent production costs.
Promotes energy-efficient equipment: Improved combustion efficiency can reduce heat losses and make better use of the energy supplied.
Supports processing capacity: The two-to-four-chamber configuration accommodates the heating requirements of gari and salt processing activities.
Improves enterprise competitiveness: Lower fuel consumption and more efficient operations can help local processors manage costs and improve their market position.
Supports agro-processing modernization: ECO SIKA offers a potential pathway for upgrading traditional processing equipment and strengthening rural value addition.
To maximize the socio-economic, environmental, and commercial benefits of ECO SIKA and support scalable adoption, governments and decision-makers should consider:
Every USD invested returns USD 0.05 net income.

Scaling Readiness describes how complete a technology's development is and its ability to be scaled. It produces a score that measures a technology's readiness along two axes: the level of maturity of the idea itself, and the level to which the technology has been used so far.
Each axis goes from 0 to 9 where 9 is the “ready-to-scale” status. For each technology profile in the e-catalogs we have documented the scaling readiness status from evidence given by the technology providers. The e-catalogs only showcase technologies for which the scaling readiness score is at least 8 for maturity of the idea and 7 for the level of use.
The graph below represents visually the scaling readiness status for this technology, you can see the label of each level by hovering your mouse cursor on the number.
